GMC SIERRA BATTERY PROBLEM

2003 GMC Sierra • 260,000 miles

Changed the abs control module under the driver side. Battery was disconnected for approximately 45 minutes or so because indid this at work and was being interrupted by the phone and dispatching hands. After I completed the job I hooked the battery up (the key was in the ignition in the off position the whole time) and attempted to start my truck. And the display said unknown driver. No locks, radio, windows, or interior lights and truck starts but instantly turns off. Was told I engaged the anti-theft. Please help? This is my wifes truck and shes upset and with all our kiddos one vehicle down is tough! What do I do?

Also, I have only one key. I also have two keyless entry and neither of those work either.
